Description

  The present invention relates to a sash that is configured to slidably store two screen doors, in particular, with a large window frame opening.

  In general, a sliding door sash is slidably accommodated with two sliding door shojis in a window frame. However, a sliding door with three sliding doors is also known in order to obtain a large opening. Thus, in a window frame configuration with a large opening, one screen door is not sufficient. Therefore, two parallel screen door rails are provided on the lower frame of the window frame, and the screen doors are incorporated into the indoor rail and the outdoor rail, respectively. When three shoji screens are grouped on one side, an opening with the size of two shoji screens is obtained, and this screen can be handled by two screen doors.

  By the way, when two screen door rails are provided in the lower frame, a groove is formed between the indoor door door rails. Moreover, since the screen door is provided on the outdoor side of the window frame, rainwater tends to enter the groove between the rails directly or through the screen door. Therefore, the screen door rail is usually formed lower than the shoji guide rail (see Patent Document 1), and a drain hole is formed at the groove bottom between the rails.

Thus, if there is a step between the shoji guide rail and the screen door rail, barrier-free correspondence becomes incomplete. Generally, sashes for two sliding door shojis are mainly used, and there is only one screen door rail. Therefore, even if the screen door rail is further lowered, it has not been a problem in practice.
Japanese Patent Laid-Open No. 9-228741

  However, in the lower frame structure in which two screen door rails are arranged, the step falls by the width of the screen door rail, so there is a possibility that the caster falls into the screen door rail portion when passing by a wheelchair, making it barrier-free. Can not respond.

  The present invention solves the above-mentioned problems, and even with a sash that accommodates three or more sliding doors, the screen door rail portion can be configured to be barrier-free by the attachment, and the rain water on the attachment is also tidy The problem is to provide a sash that can be discharged to the outside.

  In order to solve the above-mentioned problem, the invention according to claim 1 is directed to the lower frame constituting the window frame, the shoji guide rail, and the two parallel sash screen doors that slidably guide the indoor screen two screen doors. In a sash formed integrally with a rail, a screen door attachment having two screen door rails is placed on the two sash screen door rails, and the two screen door rails are placed on top of the flat upper surface of the screen door attachment. In addition, the rising part is formed on the outdoor side of these two screen door rails, and the height of the two screen door rails of the screen door attachment and the upper end of the rising part is substantially horizontal with the height of the upper end of the shoji rail. Aligning, attaching an end cap to the gap formed between the end of the screen door attachment and the vertical frame of the window frame, forming an even flat surface on the top of the screen door attachment on the end cap, On the outdoor side of the rat surface, an upstanding portion that is continuous with the rising portion is formed, and the upstanding portion is provided at an overhanging position on the outdoor side from the vertical frame, and a part of the flat surface is provided between the vertical frame and the rising portion. It is characterized by having come in between.

  The invention according to claim 2 is characterized in that, in claim 1, a fitting groove that can be fitted to a protrusion formed in the longitudinal direction of the vertical frame is formed on a side surface of the end cap. .

  According to a third aspect of the present invention, in the first or second aspect, a locking piece that can be elastically locked to the screen door attachment is formed on a side surface of the end cap. .

  According to the first aspect of the present invention, the heights of the two screen door rails of the screen door attachment and the upper end of the rising portion are substantially level with the height of the upper end of the shoji rail. Therefore, even if the sash screen door rail formed integrally with the sash is different from the shoji rail, a structure corresponding to barrier-free can be achieved.

  Moreover, since a groove is formed inside the two screen door rails of the screen door attachment, rainwater collects. The accumulated rainwater flows along the groove, moves from its end to the flat surface of the end cap that is flush with the upper surface of the screen door attachment, and further flows along the flat surface to the indoor side as a vertical frame and upright portion. From between the two, it flows down along the outer end face next to the end cap and is discharged. In this way, rainwater does not droop from the portion facing the outdoor side of the sash, but flows down from the side of the sash along the outer surface, so the appearance is good.

  As described above, according to the lower frame structure of the sash, even if the window frame has two screen door rails having a different structure from the shoji guide rail and has a wide opening, the screen door attachment is sufficient for the screen door rail portion. In addition to being able to change to a sash having a barrier-free function, a good rain finish can be secured by the end cap.

  According to the invention of claim 2, since the fitting groove that can be fitted to the protrusion formed in the longitudinal direction of the vertical frame is formed on the side surface of the end cap, the end cap is installed indoors and outdoors. There is no movement in the direction and it can be mounted stably.

  According to the invention of claim 3, since the locking piece that can be elastically locked to the screen door attachment is formed on the side surface of the end cap, there is no need to fix it with screws or the like. End caps can be easily attached.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a front view of a three-sliding door sash, and FIG. 2 is a partially enlarged cross-sectional view taken along line XX of FIG.

  In the figure, reference numeral 1 denotes a window frame. The window frame 1 is formed by rectangularly framing an upper frame 1a and a lower frame 1b made of an extruded aluminum material and left and right vertical frames 1c and 1c. The lower frame 1b has a shoji guide from the indoor side to the outdoor side. The inner rail 2, intermediate rail 3 and outer rail 4 are provided in parallel to each other. The heights of the upper ends of the rails 2, 3, and 4 are aligned substantially horizontally.

  By the way, on the outdoor side of the outer rail of the lower frame 1b, two sash screen rails 5a and 5b designed to slidably guide the indoor screen door and the outdoor screen door are formed. . The screen door rail is lower than the shoji guide rails 2, 3 and 4. By attaching a screen door attachment 15 to the sash screen door rails 5a and 5b as described later, the screen doors 11 and 12 can slide. Thus, the shoji guide rails 2, 3, 4 and the sash screen door rails 5a, 5b are different in level and have the same configuration as the existing window frame. Although it is not exactly the same as the existing one, it is a window frame configured under the same design concept as the existing one.

  Further, the inner rail 2, the intermediate rail 3 and the outer rail 4 of the lower frame 1b are slidably guided with the inner shoji 7, the intermediate shoji 8 and the outer shoji 9, respectively. The inner rail 2, the intermediate rail 3, and the outer rail 4 of the lower frame 1b support the doors 10 of the inner shoji 7, the intermediate shoji 8, and the outer shoji 9 so that they can roll. Thereby, the inner shoji 7, the intermediate shoji 8, and the outer shoji 9 can be opened / closed from one end to the other end along the corresponding rails. Moreover, the screen doors 11 and 12 are slidably guided by the sash screen door rails 5a and 5b.

  Further, as shown in FIG. 3, the two screen door rails 5a and 5b provided on the indoor side and the outdoor side of the lower frame 1b butt against the two ridges 14 provided on the outdoor side of the vertical frame 1c. It is formed at the position. Moreover, the surface of the outdoor side of the vertical frame 1c and the lower frame 1b is substantially flush.

  Next, a screen door attachment 15 is placed on the two sash screen door rails 5a and 5b except for the rail ends. The screen door attachment 15 is a member made of extruded aluminum material formed slightly shorter than the sash screen door rails 5a and 5b of the lower frame 1b, and as shown in FIGS. 4 and 5, mainly the side wall portion 16 on the indoor side. The upper part of the outdoor side wall part 17 is connected to the upper surface part 18 to form a U-shape that opens downward, and the rising part 20 is formed upright from the end of the lower bottom part 19 projecting from the lower part of the side wall part 17 to the outdoor side. The mounting edge 21 is suspended from the indoor side of the lower bottom portion 19. An upper surface of the upper surface portion 18 is formed flat, and an indoor screen door rail 22 and an outdoor screen door rail 23 are provided on the upper surface of the upper surface 18 at upper positions corresponding to the sash screen door rails 5a and 5b, respectively. Protrusions are formed. Further, on the inner side of the two side wall portions 16 and 17 of the screen door attachment 15 are engaging pieces 24 and 25 that can be engaged with the indoor screen door rail 22 and the outdoor screen door rail 23, respectively, on the indoor side and the outdoor side. Is formed.

  In addition, the height of the upper end of the screen door rails 22 and 23 of the screen door attachment 15 is aligned substantially horizontally with the upper ends of the sash shoji rails 2, 3 and 4. The top end height of the rising portion 20 is also aligned with the top end heights of the sash shoji rails 2, 3, 4 and the screen door rails 22, 23 so as to be substantially horizontal.

  In order to attach the screen door attachment 15, the sash screen door rails 5a and 5b of the lower frame 1b are dropped from above the sash screen door rails 5a and 5b. The edge 21 may be superposed on the hanging edge 26 at the outdoor end of the lower frame 1b and screwed.

  Next, as shown in FIGS. 6 to 8, an end cap 27 is attached between the end of the screen door attachment 15 and the vertical frame 1c. The end cap 27 is a member made of synthetic resin and is formed in a block shape corresponding to the cross-sectional shape of the screen door attachment 15. The upper surface 28 is flat, and a contact portion that contacts the end surface of the attachment edge of the screen door attachment 15 is provided below. 30 is formed to protrude. A fitting portion 31 that fits inside the indoor sash screen rails 5a and 5b of the lower frame 1b is formed at the lower portion of the end cap 27, and the end portion on the outdoor side rises from the flat surface 28. An upstanding portion 32 is formed, and an engaging edge 33 is formed on the inside of the upstanding portion 32 so as to protrude from the upper portion of the rising portion 20 of the screen door attachment 15 and the outdoor side surface. Furthermore, a fitting groove 34 that can be fitted to the protrusion 14 of the vertical frame 1c is formed on the outer side of the end cap 27, and a locking piece 35 having a snap fitting function is formed on the inner end surface on the opposite side. ing.

  When attaching the end cap 27, as shown in FIGS. 7 and 8, the fitting groove 34 of the end cap 27 is slid downward in a state where the fitting groove 34 is fitted to the protrusion 14 of the vertical frame 1c. It is dropped into the space between the frame 1c and the screen door attachment 15, the fitting portion 31 is fitted between the sash screen door rails 5a and 5b of the lower frame 1b, and the contact portion 30 is attached to the end face of the mounting edge 21 of the screen door attachment 15. The engagement edge 33 may be further engaged with the upright portion 20 of the screen door attachment 15. When the end cap 27 is pushed downward, the locking piece 35 finally formed on the inner end surface is elastically locked to the lower side of the upper surface portion 28 of the screen door attachment 15 and does not depend on a fixing means such as a screw. Even the whole is easily fixed.

  When the end cap 27 is attached, the upper flat surface 28 of the end cap 27 and the upper surface of the screen door attachment 15 are flush with each other. Further, the engagement edge 33 is in contact with the end of the rising portion 20 of the screen door attachment 15 and is continuously arranged with the rising portion 20. In addition, since the fitting groove 34 of the end cap 27 and the protrusion 14 of the vertical frame are fitted, the end cap 27 does not move indoors and outdoors and can be stably attached.

  When attached as described above, as shown in FIG. 9, the upper flat surface 28 of the end cap 27 constitutes a substantially horizontal plane flush with the upper surface of the upper surface portion 18 of the screen door attachment 15, and the upper flat surface The standing portion 32 is formed as a barrier on the outdoor side of 28, but the outer end portion of the upper flat surface 28 is a drooping surface that is cut off as it is.

  Although the end cap 27 has no screen door rail, there is no hindrance to the sliding of the screen door.

  According to the above configuration, as shown in FIG. 8, the height of the upper ends of the two screen door rails 22 and 23 of the screen door attachment 15 and the rising portion 20 is substantially horizontal with the height of the upper ends of the shoji rails 2, 3 and 4. Are aligned. Therefore, even if the sash screen rails 5a and 5b formed integrally with the sash are different from the shoji rails 2, 3, and 4, the structure corresponding to barrier-free can be achieved.

  Moreover, since a groove | channel is formed inside the two screen door rails 22 and 23 of the screen door attachment 15, dust and rain water accumulate there. As shown in FIG. 9, the accumulated rainwater flows along the groove, moves from the end of the rainwater to the flat surface 28 of the end cap 27 flush with the groove bottom, and further moves indoors along the flat surface 28. The flowed material falls to the lower frame 1b and is discharged from a drain hole (not shown) of the lower frame 1b. On the other hand, the thing which flowed to the outdoor side flows to the inside or the outside due to the upright portion 32 becoming an obstacle. What has flowed inside falls to the inside of the rising portion 20 and falls from a drain hole (not shown). Moreover, since the rising part 20 has protruded to the outdoor side rather than the vertical frame 1c, what flowed to the outer side is between the vertical frame 1c and the upright part 32, and the outer side of the end cap 27 is shown as an arrow. It flows down along the end face and is discharged. Similarly, dust can be swept out of the end cap 27.

  In this way, rainwater does not droop from the portion facing the outdoor side of the sash, but flows down from the side of the sash along the outer surface, so the appearance is good.

  According to the lower frame structure of the sash, even if it is a window frame having two screen door rails 5a and 5b having a different configuration from the shoji guide rails 2, 3, and 4 and having a wide opening, the screen door is attached by the screen door attachment 15. The rail portion can be changed to a sash having a sufficient barrier-free function, and rainwater and the like can be discharged to the outside by the end cap 27.

  The lower frame 1b structure can be retrofitted to an existing sash, and the conventional three-panel sliding door sash can be made barrier-free without changing the design.

  An inter-rail attachment 36 is attached between the outer rail 4 and the intermediate rail 3 and between the intermediate rail 3 and the inner rail 2 of the lower frame 1b. That is, as shown in FIGS. 2, 5, and 8, protrusions 37 are formed on the side surfaces of the outer rail 4, the intermediate rail 3, and the inner rail 2, whereas the rail-to-rail attachment 36 is between the rails. As shown in FIG. 5, the rail portion along the longitudinal direction from the center of the stepped plate 38 having a width substantially the same as the size and a size substantially the same as or slightly shorter than the size between the vertical frames 1 c and 1 c on both sides. 40 is formed in a protruding manner, a locking groove 41 is formed on the outdoor side of the stepped plate 38, and a protruding piece 42 is formed on the lower side on the indoor side. The rail-to-rail attachment 36 fits the outdoor side locking groove 41 of the stepped plate 38 into the indoor side protrusion 37 of the outer rail 4 or the intermediate rail 3, and then attaches the indoor side end of the stepped plate 38. What is necessary is just to attach by mounting on the protrusion 37 of the intermediate rail 3 and the inner rail 2 on the outdoor side. In the mounted state, the height of the rail portion 40 is set to be the same height as the other rails 2, 3, 4 at a substantially horizontal level.

  According to the above configuration, the rail portion 40 is disposed between the outer rail 4 and the intermediate rail 3 and between the intermediate rail 3 and the inner rail 2, and the gap between the outer rail 4, the intermediate rail 3, and the inner rail 2 is narrow. Therefore, when it moves with a wheelchair, it can move smoothly, and the caster does not fall between rails, and it can cope with barrier-free.
